SPECIFICATION forming part of LettersP'atent No. 282,174, dated July 31, 1883.

Application filedOc tobet 30, 1882. (No model.)

To all whom) it may concern Be it known that I, MERRITT H.- DEM NT,

of the city of Ghicago,county of Cook, and

ing Machines, whichimprovement is fully set forth in the following specification, reference being had to "theaccompanying drawings,

which form a part hereof.

specifically pointed out in the claims.

My machine consists, mainly, of a revolving I cylinder and type-wheel, keys, rods, and cams. 1

The cylinder is placed upon a suitable shaft running in hangers secured to a table or base- 3 plate, with a pulley at one end, by means of 3 which power may be applied. Any desirednumber of longitudinal grooves are cut in the cylinder, in which are placed bars or rods capable of sliding, so asto protrude from the end of the cylinder over the type-ring. The type-ring may be constructed in various ways, the type being set radially in a ring or wheel which may be concentric with the cylinder,or on a separate shaft connected by gear-wheels, which make it revolve at the same rate as the pins on their inner ends. sisting of the same number of keys as there are rods is placed beneath the cylinder.

tween the cam and the typering is placed the I paper strip, inasuitable groove, as a guide, with aforked spring above it. Asthe rods strike I the cam and are thrown upward they press the'paper strip uponthe type, and an indentation is made therein by the type, The paper, meanwhile, is pulled along in its groove as long as it isheld between the rod and the type.

The bars are provided with "canrj A key-board 0011- The key-bars are pivoted near their centers, so that; by depressing one end the other end will be.

The forked spring throws the paper from the, type afterthe rod isreleas'ed.

Ina former application I have described and claimed the combination of the cylinder, sliding rods, and the cam for pressing the rods on the paper, and I make no claim therefor in this application. y

To give each letter its proper space, I make 1 the rods, or atleast that portion which passes My invention relates to the devices and combinations as hereinafter described, and I over the cam, of different widths, according to the widths of the letters they operate upon. It will be seen that the wider the rod the longer it will be in passing the apex of the cam, and hence the longer it will hold and the farther it will pull the paper, "so that, in the case of the capital letter W, a very wide rod is provided, while thelower-case, i, 7 will require a very narrow rod. 'Where several rows of type are used, each rod inayhave two or more places of difi'erent'widths corresponding to the different letters upon which it operates. In such case the cam is made to slide in a groove, so as to bring it under the portion of the rod correspondingto the row of type to be operated upon. For instance, if the first rod shall operate upon the capital A in one row of type,

the small a in the second row, and the be shifted so that the cam will operate upon the desired one of the three spaces. The cam is shifted by means of a lever or bar connected with the apparatus for shifting the type-ring, or by an independent connection with a pedal, upon which the operators foot is pressed in shifting. I

I prefer to make the cam upon the end of a plate, A, the other end connecting, by means of a slot and pin or other device, with the mechanism for shifting the type-ring, the under portion of the support for the cam B being cut away so as to form a groove, through which the cam-plate A{ may slide. Inthis form the cam may be made narrower than when fixed, and will require to be shifted but a short distance to pass from one widened space 011 the bar to another.

The, mechanism for shifting the type-ring may be constructed in: a variety of ways. I prefer to use a grooved ring placed upon the shaft and connecting withthe type-ring and revolving with it. In connection with this is a yoke, in each arm of which is placed a pin fitti'ng and running in the grooved ring. This yoke is formed upon the end of a shifting-bar, which is pivoted to the base-plate, and to which is fixed ahorizontal arm extending under the base-plate, which is, in turn, connected with same time.

than the type rows.

the pedal by means of a chain or cord or other suitable device. The end of the shifting camplate may be attached to this shifting-bar, so that the operator, in pressing upon the pedal, will shift both the type-ring and the cam at the The type-ring being requiredto be shifted a farther distance than the cam, it is connected with the shifting-bar at a farther distance from its pivot than the cam-plate, which requires less movement, inasmuch as the widened spaces on the bars will be closer together This feature of a shift ing cam will probably be only used on machines when different-sized fonts of type are used. There only one size is used, the Roman capitals and lower case, with the ordinary punctuation-marks, may be placed in one row or ring and the Italic capitals and lower-case in the next row, and one set of bars and a fixed cam will answer, for the bar operating upon the Roman capital A will also operate uponthe Italic capital A, and so on through the alphabet; and it isonlynecessaryto have the Italics so cut as to be of exactly the same width as the Roman letters. Figure 1 is intended to represent this form of the machine, although rear side of the rods as they revolve.

- ing. same elasticity, and the rods do not work up and a full double alphabet is not shown in each row. In the grooves under each of the bars a spring is placed, to hold the bar in the proper position when not printing. Such springs have also been used to throw the bars off the paper after print- These springs do not always retain the down in the grooves with the same ease, and the result is that when a spring is weak or a rod works slowly it will not be promptly thrown from the type after printing, and will consequently drag the paper too far and give the letter printed upon too much space. To prevent this and secure absolutely accurate spacing, I place a cam in position immediately after the first cam, and where the rod will strike it after it shall have passed the first cam, and printed, and be taken off the paper promptly by positive action. In connection with this cam, the rods, for a space of about one-eighth of an inch (more or less) from the ends, are made of uniform width, and true to or even with the This portion of the rod is not made quite so high as the part which presses the paper on the type, so as to leave room between it and the type for the cam to overhang it. The second cam is placed from the apex of the first cam just the width of the rods where they are of this uniform width, so that no matter how wide the pulling the paper the required distance without puncturing the face of the strip, I place on the type-wheel, in the proper position to be operated upon by the rod connecting with the space-key, a blank type or pin with a fiat or slightly-convex head .of about the same height or a little shorter than the type-head. This may be milled or roughened. Then I place upon the inner side of the rod, or on that portion which presses upon the paper, one or more small pins or points or suitable milling, the operation being substantially the same as in printing a letter, except that the indentation is made on the reverse side of the paper, and by the rod instead of the type.

This method of spacing between words is preferable to other methods, because it makes no indentations in the face of the paper into which the stereotyping-metal will run, and thus cause unnecessary prominences on the plate or bar 9 when cast from the strip which will print. The rods, after printing, are returned to the cylinder by a third cam placed after the other two cams in such a position that the ends of the rods will strike it and be pushed back by it.

This is an improvement over the present mode of having a series of pins running in a doublegrooved collar in which there is also a cam, for the reasons that the pins are liable to break off and clog up the groove, and the collar adds greatly to the friction and complication of the machine. By the improvement suggested the pins and collar are dispensed with entirely, as the cam operates directly upon the ends of the rods and there can be no breaking or clogging. To permit the rods to be depressed on the types, they are each provided with a joint, and the grooves in which they lie are made deeper at the printing end of the cylinder, the rods being held in their natural position,-when not printing, by suitable springs, and prevented from going beyond by bands. In this there is no novelty, the same mechanism being already in use.

Where the type-ring is placed on a separate shaft connected by gear-wheels with the cylinder-shaft, the same cams and rods may be used. The positions of the cams are reversed, the rods being pressed outwardly instead of inwardly, and the paper guide and spring are placed between the outer edgesof the rods and the type-wheel. The same results will be accomplished in this way as where-the cylinder and type-ring are concentric.
